Code page identification system |
(57) This disclosure relates to a comprehensive method of codifying the different encoding
schemes that are used for graphic character representation, resulting in a single
identification mechanism that is used in conjunction with a corresponding registry
to simply and uniquely identify the scheme used. The mechanism comprises such a short
form identifier having the capability of acting as a short form (alias) for its corresponding
list of component identifiers; acting as a short form for a collection of specific
component identifiers having a specific property; allowing special meanings to be
conveyed in relation to tagging of data with the code identification; and allowing
bridging to existing systems that use only some components of the code identification.
